Feature Packed

Charges host computer up to 60W Supports three HDMI displays USB Connectivity icon
Charge Display Connect
  • Up to 60W of USB Power Delivery

If your device supports USB Power Delivery (USB PD), this docking station supports up to 60 watts (60W) of charging to your host device.

This means you won’t need to use the charger that came with your laptop when you’re at your desk, on supported hosts. The one USB-C cable from the dock is all you’ll need to stay charged and connect all your devices.

Some laptops may require more power than this dock provides (60W). The Dell XPS 15 9550/9560 and Precision 5510/7510, for example, will display a warning during boot if connected to a 60W power adapter, rather than a Dell 130W power adapter. These systems may still charge, but at a slower rate, and may use battery power when under heavy load.

  • 1x HDMI (Alt Mode)
  • 2x HDMI (DisplayLink)

With one USB-C (USB Type-C) cable connected to the dock, overcome the limited number of display outputs and ports on your device. This dock connects up to three HDMI displays on supported devices.

HDMI 1 supports resolutions up to 4K 30Hz. HDMI 2 and HDMI 3 support resolutions up to 1920×1200 @ 60Hz each

For USB-C ports that do not support Alternate Mode video output will be limited to displaying through the two DisplayLink HDMI ports.

Note: HDMI can be adapted to DVI or VGA with separate adapters or cables, but is incompatible with DisplayPort inputs on displays.

  • 6x USB 3.0 Ports
  • 1x Gigabit Ethernet
  • 1x 3.5mm TRRS Headset Port*

Many laptops are removing or drastically reducing the number of ports available.

Get back your USB, audio, and network connections. This dock also makes it easy to leave your peripherals plugged in at your main work area, and reconnect them, with one cable from the dock.

* TRRS Headset port supports stereo headphones and mono microphone on a single 3.5mm four-conductor connector, additional adapters may be necessary to connect some headsets with separate stereo headphone and microphone connections.

Port Features, Limitations, Notes, and Terminology

USB-C Alternate Mode (Alt Mode) is a new feature introduced with USB 3.1, allowing USB-C ports and cables to carry video signals directly from a device over a USB cable. Alt Mode video comes directly from the graphics card or integrated graphics processor on a device, meaning outputs from an Alt Mode video port have the full graphics acceleration of your system. Not all systems with USB-C support this functionality.

HDMI 1 (Alt Mode) allows for a maximum output resolution of 4K 30Hz (3840×2160 @ 30Hz). Lower resolutions such as 1920×1200, and 1920×1080 (1080p) are supported at 60Hz. The HDMI 1.4 connection on this dock is provided by converting DisplayPort Alt Mode to HDMI 1.4.

HDMI 2 and 3 (DisplayLink) allows for a maximum output resolution of 2K 60Hz (1920×1200 @ 60Hz). The HDMI 1.3 connection on this dock is provided by the DisplayLink DL-3900 USB graphics chipset.

DisplayLink is a technology that allows compressed data of various types to be sent over USB data connections. The DisplayLink DL-3900 chipset in this docking station connects all the data and video connections, other than the “4K” HDMI 1.4 connection, on this dock.

There are a few important limitations of DisplayLink technology. DisplayLink uses a proprietary compressed video stream that is partially generated by both your computer’s CPU and GPU, and is a “virtual” video adapter. Because the video is compressed and packetized as data, then reassembled by the DisplayLink chip, the pacing of new frames of video can be inconsistent, particularly if large portions of the content being sent through DisplayLink is changing (such as with video playback).

Because of how DisplayLink provides video, video outputs provided by DisplayLink technology should only be used to display content like office applications and web browser windows, not games or video content.

HDCP is not supported, this means protected content such as Netflix, Amazon Video, YouTube Premium, Hulu, Blu-ray videos, and other protected content, either may not work or will play at a lower resolution, depending on the content provider.

Some USB-C ports Windows Laptop computers are labelled as Thunderbolt 3 ports. Thunderbolt 3 ports are USB-C ports with additional functionality that are also compatible with this docking station.

USB-C Power Delivery (USB-C PD) is a standard introduced with USB-C that provides enough power for many mobile devices and laptops. This dock is able to supply up to 60W of power to a host. Some laptops may require more power than this. The Dell XPS 15 9550/9560 and Precision 5510/7510, for example, will display a warning during boot if connected to a 60W power adapter, rather than a Dell 130W power adapter. These systems may still charge, but at a slower rate and the battery may discharge under heavy system loads.
